Wisdom tooth pain: which teeth actually need removing

Not every wisdom tooth needs to come out

A wisdom tooth is not a problem simply because it is a wisdom tooth. Plenty come through straight, bite properly against the tooth above, and can be cleaned with an ordinary toothbrush. Those are working teeth. There is no reason to remove them and no reason to pay to have them removed.

So when a clinic glances in your mouth, counts four wisdom teeth and recommends taking out all four, be careful. That is not a diagnosis. The honest first answer to do I need this tooth out is let us look at the X-ray, and after the X-ray the answer is sometimes no.

The wisdom teeth that genuinely should be removed

There are four situations where removal is the sensible answer rather than the profitable one.

Infection that keeps coming back

When a wisdom tooth is only half through, a flap of gum sits over part of it. Food and bacteria get underneath and cannot be brushed out. The gum swells, the area tastes foul, and opening your mouth becomes difficult. Antibiotics settle that down, but they do not remove the flap of gum. Once it has happened two or three times, it will keep happening.

Decay that cannot be cleaned or repaired

Wisdom teeth sit at the very back of the jaw, often at an angle. A cavity in a reachable wisdom tooth can be filled like any other, and one of our dental fillings is worth doing. If neither your toothbrush nor an instrument can reach the decayed surface, filling it only postpones the same conversation for a year.

It is pushing into the tooth in front

An angled wisdom tooth leans against the molar in front of it. That contact point cannot be cleaned, and decay starts on the back surface of a healthy second molar, a tooth you chew with every day. Losing that molar is the bigger loss. When the X-ray shows this, removal protects the tooth in front.

Impacted and doing damage

Some wisdom teeth stay buried in bone. Buried and quiet is not the same as buried and harmful. If the film shows a cyst forming around the crown, or the buried tooth eating into the root of its neighbour, it should come out. A tooth sitting still and causing nothing is a different case.

The wisdom teeth to leave alone

A wisdom tooth that has come through straight, meets a tooth in the opposite jaw, has healthy gum around it and can be brushed is a normal tooth. It stays. Removing it would mean pain and swelling in exchange for nothing.

A fully buried wisdom tooth that has never caused symptoms can also be watched rather than removed. Taking out a deeply buried tooth is surgery, and nobody should accept surgery for a tooth that has never given trouble.

One more case is worth naming. People arrive certain their wisdom tooth is the problem, and the examination finds a cavity in the molar in front, or gum inflammation from built-up scale. The pain is real. The cause is not the wisdom tooth. That is one reason a dental check-up comes first.

Being told you may as well have them out while you are young is not a reason. Neither is the idea that removing wisdom teeth straightens crowded front teeth.

Why the X-ray comes first, every time

Above the gum you see a fraction of the tooth. The X-ray shows the rest: how many roots there are, whether they are straight or hooked, the angle of the tooth, how much bone covers it, and how close the roots sit to the nerve running through the lower jaw. That last point decides how the tooth has to come out.

The X-ray also decides the price. Any clinic quoting a firm wisdom tooth figure over the phone, without seeing a film, is guessing at your expense.

Why the price varies, and when you hear it

A straightforward wisdom tooth — fully through the gum, gripped with ordinary instruments, out in a few minutes — is priced as a standard tooth extraction, because that is exactly what it is. There is no separate wisdom tooth removal charge here.

A surgical case costs more, and it should. The gum is lifted, a little bone may be removed, the tooth is often divided into pieces rather than forced out, and stitches go in at the end. The exact number is given to you after the X-ray and before treatment begins. It is not a figure you discover when you stand up. Everything else we charge is on the price list.

The cases we send elsewhere

Some wisdom teeth are genuinely difficult: roots wrapped around the nerve, teeth lying sideways deep in the bone, or a medical history that makes this a specialist job. In those cases we say so and refer you to an oral surgeon. Starting a difficult extraction and stopping halfway is the worst outcome for a patient, and we will not do it.

We take cash and card only, and we do not bill insurers directly. You are given a stamped invoice and a completed reimbursement form to claim the cost back yourself.

Aftercare, and the warning signs of dry socket

Bite firmly on the gauze for thirty to forty-five minutes. Leave the area alone for the first day: no rinsing, no straws, no smoking. Eat soft food on the other side. From the second day, rinse gently with warm salt water after meals. Take your painkillers before the anaesthetic wears off rather than after. Swelling usually peaks on the second or third day and then settles.

Dry socket is the complication to know about. The blood clot breaks down and leaves bone exposed. It usually starts three to five days after the extraction, and the pattern is distinctive: the pain gets worse rather than better, it throbs deeply and spreads towards the ear and jaw, there is a bad taste or smell, and ordinary painkillers barely touch it. It needs the socket cleaned and a dressing placed, so telephone the clinic rather than waiting it out. Smoking is by far the biggest risk factor.

If the pain eases a little each day and the swelling is going down, healing is going the way it should.

If a wisdom tooth has been aching, the useful next step is a look and a film, not a decision made in advance. We will tell you which of the cases above your tooth falls into, what it costs, and whether it needs doing at all.
